Engine Oil Pressure Light
Notice: Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced.
Always follow the maintenance
schedule for changing engine oil.

The oil pressure light should come on briefly as the engine is started.
If it does not come on, have the vehicle serviced by your dealer.
If the light comes on and stays on, it means that oil is not flowing through the engine properly.
The vehicle could be low on oil and might have some other system problem. See your dealer.
